Numerous and often troublesome, occasionally destroying swine, of 

 which they are exceedingly fond. Judging from their tracks in the 

 swamps, they must not only be exceedingly numerous, but some of 

 them of enormous size. The several .--kins seen by me were all in- 

 tensely black.*

Abundant almost everywhere. Not so numerous along the Lower 

 St. John's as in the more unsettled districts further south. As re- 

 marked by Professor Baird, the Florida deer are considerably smaller 

 than those of the Northern States ; so much so that it is a fact of 

 common observation.

I learn from Mr. Maynard that the manatee is still quite common.in 

 Indian River, where they are often caught in nets. They come into 

 the river at niglit to feed on the mangrove bushes. Mr. Maynard did 

 not meet with them in Mosquito Lagoon, which he traversed nearly its 

 whole length, and he thinks they do not occur there. 



The manatees of America and Africa seem to be very closely allied, and 

 to number at most but two species. Those of the same species also appear 

 to be exceedingly variable in their osteological characters. Dr. J. E. Gray, 



* In my recent paper in this Bulletin, cited above, I have discussed the mutual re- 

 lationship of the numerous supposed species of lan.l bears <>f the northern hemisphere. 

 The close affinity between the hears of Northwestern America and Northeastern Asia 

 is especially noticed; but at that time I was nut aware that Temminck, in the Fauna 

 Japonica, had referred the large land bear of Japan to the U. fa-ox of authors, or to 

 the so-called "grizzly bear" of Western America. Tliis indicates the very close affinity, 

 in this author's opinion, of the Japan and American bears.
